Fuze doesn't use 3G after flashing Romeos?

So I flashed Romeos2 to my new Fuze. It works fine, and the 3G logo went away and was replaced with the H logo. However, now when I use data, it is painfully slow. I'm assuming that its using edge - anyone have this issue? Any solution? I have the PDA data plan.

is it possible tha ROMeOS is meant for euro and asian Touch pro's meaning it wont get the 3G working in the US
TBH you should post this in the ROMeOS forum

You should also make sure that your data settings are set up properly for AT&T. They may not be after the flash.

do a search for htc connection setup. that will give you the proper network settings.

Isnt the H for HSDPA which is faster than 3G? Mines been doing the same thing.

i have the same problem. (no 3G or HSDPA only GPRS/EDGE)
tried 3 different roms and 3 different radios (with the .32 i didn't get any http connection at all, but icq etc. worked)
i have an german tp without branding ...

solved my problem ... 3G was deaktivated (default by the provider [o2])

so I did a search and found multiple .cab files for it. How do I know which one is good for AT&T? Does anyone know if ROMeOS2 supports AT&T connection properly?

H stands for HSDPA, which is a technical term for 3G.
E stands for EDGE.
G stands for GRPS.
When I installed ROMeOS on my Fuze, there was a connection window that popped up that had country and carrier drop down boxes. Try going through the connection settings and see if you can find something like that.

HSDPA is the high-speed version of UMTS/WCDMA/3G.
G stands for GPRS.
E stands for EGPRS or EDGE meaning high-speed GPRS.

I was just logging in to correct myself! Thanks ;-)

This is incorrect. 3G is the blanket term used for high speed mobile data. If you have an ATT branded phone and it shows 3G then you are on a UMTS (universal mobile telecommunications system) network which is slower than HSDPA (which stands for high speed download packet access) but still faster thank EDGE or EGPRS or whatever you want to call it. However, when I tested RomeOS on my Fuze, I too got the H symbol instead of a 3G one. I am fairly certain that in order to make the Fuze less confusing, an ATT branded Fuze will show 3G for both UMTS and HSDPA. I am now back on a modified ATT ROM by NotaTreoFan and it shows 3G when I am in the same spot at my highschool's cafeteria as where RomeOS showed an H. Hope this clears things up (or possibly makes them more confusing).
Edit: Looks like we all wanted to correct it

Turning on HSDPA?

I've seen screenshots of Captivates homescreens from you peoples showing an H instead of just 3G. May I ask how you enabled this? Thanks in advance!

HSDPA and 3G are the same thing (i'm pretty sure)
or more technically speaking, HSDPA is one half of 3G, with HSUPA being the other half (HSDPA=download, HSUPA=upload)...
can anybody correct me if i'm wrong?

You're correct. AT&T requires all its 3G phone to display 3G instead of any other icon. Often times, ppl find ways to replace it with the native 3G icon, H, which is widely used by rest of the world. But that makes no difference in actual connection speed.

this is correct. when referring to both of them together they are commonly called just HSPA.

"3G" is the common short abbreviation for UMTS. HSDPA is an update to UMTS that gives faster download speeds (a version is widely deployed on AT&T). HSUPA is a protocol upgrade that enables faster upload speeds (installing HSUPA equipment borked upload speed on AT&T recently). Combining the two is called HSPA. HSPA+ is an update to HSPA that's even faster. T-Mobile is planning on rolling this out. LTE (AT&T's 4G pathway) is totally unrelated to HSPA.

Thanks for your replies! I appreciate the schooling

This is the correct post.
Also, I'm certain AT&T doesn't disallow the H icon because I've seen screenshots of the Captivate with that icon.
However, at the same time, I have a -51 dBm signal and no HSUPA which I know I should be able to get here because my iPhone 4 got it. Something is going on, but I'm not sure what yet.
Edit: Nevermind, it sounds like I'm wrong. In the manual there's no mention of an H icon. There's also no mention of HSUPA. I think we just got screwed by AT&T. What a surprise.

I'm pretty sure AT&T does disallow use of the H icon. They did on my Fuze. The reason is that there's ALWAYS confusion when people don't have a good operational knowledge of the protocol names. There's always someone on the EnergyROM or Cyanogenmod threads asking why "only" H comes up when they expect 3G.
Anyway, I have an AT&T band Nexus One as well as a Captivate. The N1 is definitely HSUPA compatible. I just tried speedtest.net a few times and got an average of 2.5M down and 175k up (5 runs no run over 256k) in midtown Manhattan. On my Captivate I'm getting ~4M down and 200k up. Upload speeds are about the same, probably limited by AT&T's current (under) capability.
I don't have access to an iPhone 4, but if you do, could you do a few runs on the speedtest.net app on both devices from the same location and let us know the results? At this point, I'm pretty convinced it's the HSUPA equipment screw-up at AT&T not lack of HSUPA on the phone.

That's what I was saying. My iPhone 4 got HSUPA here with no issue at all. When everyone else's HSUPA had issues, I still had no problem at all. So unless HSUPA decided to die in my area the day I returned my iPhone 4, I don't think the Captivate has it.

When did you return it? The iPhone 4 was released on June 24 and the AT&T HSUPA issue cropped up around July 6th or so. That's when my Nexus went from over ~1M up to ~200k up. If you gave it up after July 6, what sort of upload speeds were you getting? What sort of speeds are you getting now on the Captivate? Not trying to grill you or anything, I'm genuinely curious.

[Q] Data speeds?

So I know all the issues with older 2g sims affecting speeds, I called tmobile, and they said that I was in fact registered with a 2g sim, so I had them activate the sim that came in the box, but I have no improvement in speed. I'm still getting nowhere above 2mbps, most of the time around 1. I know I have a 4g data plan, they added that when I got the phone for immediate activation, not next billing cycle. Even in areas where my old mytouch 3G slide got 4 mbps on the 3G HSPA network, I can't get much above 2 on the HSPA+ network. What gives? If the new 4g sim and data plan aren't working, what's the issue here? Anyone else having issues?

Are you sure that you're connected to HSPA+? And, even if you are connected with good reception to a HSPA+ tower, that doesn't mean that the tower has good bandwidth backhaul. If its a low traffic tower, T-Mobile might not want to pay for a large amount of bandwidth for it.

I suppose I can't be positive, but the icon says 4G. Although I've never seen a 3G icon, only G, 2G, and 4G, meaning they probably just replaced the 3G icon with the 4G icon since the phone can't technically display a different icon for HSPA and HSPA+, can it? I've never seen a 3G icon so I might just be connected to 3G. But even in populous areas, like downtown, at night, I top out at 4, MAYBE 5 mbps. I've heard people getting 4 or 5 on a bad day, 7-8 average and 10-12 if they're lucky. I'm wondering where that's at, maybe it's a flaw in the stock rom and an AOSP or other custom rom would be better. I seem to remember having bad speeds on sense on my Slide too.
During data transfer, I went to the about phone>network menu, and mobile network type reads HSDPA and then reverts to UMTS after a period of inactivity. It does not specify HSDPA+ though, it just says HSDPA. I understand that the 3g and 4g networks on tmobile are technically one and the same, HSDPA+ is just an advancement of the 3G technology, but I'm wondering if something just isn't clicking and the phone isn't taking advantage of HSDPA+. I checked the coverage map, and the entire region I live in, minus a few rural areas, are supposed to be covered by 4G data.

Switching between UMTS and HSPA bug

An almost identical topic already exists in HTC One S section (Radio UMTS/HSPA switching bug (3g/4g)), but I was thinking that maybe there is a different possible fix for Blaze 4G.
I am currently on the AT&T network using Straight Talk SIM. On the status bar it displays 3G with enough bars, but from time to time it stops receiving data in the middle of the transaction. When it happens, the mobile network type is shown as UMTS under "About phone" -> "Status". When it switches back to HSPA, the data resumes. It really messes up my browsing a lot
When I was still on T-Mobile, it did not seem to happen, as the connection was either "4G" or E (mobile network types HSPA+ or EDGE, respectively). I never noticed UMTS in the phone status while using T-Mobile.
One of the reasons I chose Blaze 4G is because it supports both AWS and 1900 bands, so it can work on AT&T and T-Mobile networks. As we know, T-Mobile coverage is not great, so the connection often switched from "4G" to edge. Being on AT&T, the connection firmly stays on 3G, but now I have this annoying bug.
Your input and suggestions would be highly appreciated! By the way, I am using a stock ROM with root.

I have had the same issue with my GS3 as well as my S2 and Sensation, all on T-Mobile. It is something I've noticed. Another thing I noticed, that is shady on T-Mobile's end, is that they show "4G" even if it is on UMTS.

Blaze only has 4g, E, and G, while on T-Mobile that's why it displays 4g while in umts, Umts is 3g and since there is no 3g icon it shows as 4g, hspa+ is "4g"

Is that shady? UMTS Band IV (AWS) provides HSPA+ service. Looks like 1700MHz will be split 50/50 for GSM and H+ coverage, and teh 1900MHz will be split LTE/H+ by next year.
TMO said:
As part of its transition to deploy LTE on its 1700 MHz spectrum, T-Mobile will refarm its PCS spectrum to support both 2G GSM services and HSPA+ services. In a recent FCC filing, T-Mobile said by mid-2013, its expects half of its 1900 MHz spectrum to be devoted to GSM while the other half will run HSPA+ services, and that by then half of its AWS spectrum will support HSPA+ and the other half LTE.

I am using a stock radio because it supports both 1700 MHz and 1900 MHz bands (Tmo and AT&T) - that is why I bought this phone in the first place. I am not sure there are other radios around for my phone, and even if there are, I am not sure what benefit I would get from flashing a non-stock radio. Very few phones support bands for both GSM providers in the USA; usually, it is either Tmo or AT&T.
On a another note: I got a Tmo SIM card from Straight Talk, and now I do not have this UMTS switching bug. The coverage is a bit worse, but where I have HSPA+, it is still 2-3 times faster than what I got from AT&T HSPA network.

It is not surprising, as T-mobile is rolling out HSPA+ on 1900 MHz band. It will be happening more in the future as more areas will be re-farmed. Since there are only few T-mobile phones that can support 1900 MHz, other users will not see it happen. On the other hand, those few with iPhones on T-mobile network can finally see 3G.
What puzzles me is why it shows 3G instead of "4G" on 1900 MHz band right now? Do they need to upgrade this band to HSPA+ during re-farming?

Yep, it absolutely does on dark knight build 8.
Oh you guys are talking about ...stock..?
Yeah no 3g icon on stock as T-Mo views all 3g as 4g now. There's no 3g icon on ANY 4g T-Mo phone's stock rom (with a T-Mo sim card). It is how they claimed to have the 'largest 4g network' during that ad campaign. Funny how T-Mo no longer claims that (or is no longer allowed to claim that)....
Here where I live I only have 3g. I have verified this using speedtest where I have never had more than 1.7 down/ 400 up. In Minneapolis I know there's 4g service as I have had speeds as high as 11 down / 2 up and average 8 down 1.5 up. All 3 of those statements are confirmed using Dark Knight build 8 as I have a 3g icon here at home and a 4g icon when I am in Minneapolis. The whole drive to Minneapolis showed '4g' on my wife's Sensation 4G. No, I am completely positive there's no 3g icon in the stock rom for any newer T-Mo 4g phone. If there is a 3g icon on any 4g t-mo phone (using T-Mo service), by all means educate me.

There obviously is a 3G icon as in the screenshot i posted. This rarely happens in the specific area I am in a lot (Gym) but my phone is totally stock and always shows 4G everywhere else. Let the screenshot educate you...

[Q] How to get 3G/4G with unlocked Blaze on AT&T

I bought one of these phones, rooted it, unlocked it, and installed CM9. I love the phone and OS, but I cannot get the 3G/4G to work on AT&T. Any ideas?

Yeah. The data network is incompatible. Different frequency.
Sent from my SGH-T769 using xda premium

Yeah I think all you can get is 2G (edge) on AT&T with the blaze.

I can say from first hand experience that the blaze works great with AT&T's 3g service. I bought this phone last week, unlocked it, and swapped in the sim from my old Aria and have been using it with CM10 ever since. Data speeds are around 3 to 6 Mb/s down and 1 Mb/s up, and voice and text messaging works fine.
For a more technical answer, AT&T uses the 850 mhz and 1900 mhz frequencies for UMTS (3g), and T-mobile uses 1700 mhz and 2100 mhz frequencies. The blaze supports UMTS on all of these frequencies so there are no technical roadblocks to using this phone with AT&T. http://www.phonearena.com/phones/Samsung-Galaxy-S-Blaze-4G_id6824
As for your problem of not getting 3g working, I had similar issues when first switching the sim card (especially on the stock rom). Check that your APN matches the one your old phone was using. On the stock rom, the phone did not auto detect the correct APN and this caused the 3g to not work. CM10 detected the correct APN right away though. Also, try turning data off and on or even rebooting the phone once you've checked your network settings.

I sold my other phone and no longer have it. Please confirm your APN settings, and how do I change them?

The blaze has all the frequencies necessary for it to do HSPA (3G/4G) on AT&T's networks.
You'll likely want to change the APN. On CM9/10, go to Settings -> Wireless & Networks + More... -> Mobile Network Settings -> Access Point Names.

I was careful in selecting this specific phone because of its compatibility with AT&T HSPA bands. I have tried the suggested tweaks to the APN settings within both CM9 and CM10, but I still get no visual notification that the phone is operating in 3G or 4G mode. The areas in which I have used the phone consistently provided 3G and/or 4G coverage consistently with my prior BlackBerry 9860.
Any additional tips/tricks would certainly be appreciated. I know this phone is capable of so much more than it's providing me at this point.
